The Real Housewives of Atlanta alum Kim Zolciak is breaking her silence after her ex, Kroy Biermann, filed for full custody of their four minor children. Biermann, 40, filed for custody on Monday, March 30, in Georgia, calling Zolciak's parenting into question, per court documents viewed by Us Weekly. The former NFL star claimed that Zolciak had been out of the country for weeks at a time and that one of their minor children was bitten by a dog while in her care.
